Inside the ZincFive SPAC Deal: Valuation, Dilution, Risks
ZincFive is a Portland-area battery company going public through a merger with Spark I Acquisition Corp (NASDAQ: SPKL), with the deal still pending and expected to close in the second half of 2026. The bull case is AI/data center power demand; the bear case is dilution, redemptions, and a business that is still burning cash.

Company Overview
ZincFive is a Tualatin, Oregon-based company founded in 2012 that sells immediate power solutions for mission-critical infrastructure, with a sharp focus on data centers and AI infrastructure. Its core technology is proprietary nickel-zinc (NiZn) battery chemistry, which it positions as an alternative to lead-acid and lithium-ion systems. The company says its products offer higher power density, a smaller footprint, improved safety, and lower total cost of ownership, while eliminating thermal runaway risk and reducing cooling requirements.
Its product lineup includes BC Series UPS Battery Cabinets, a NiZn Retrofit Kit, NiZn In-Rack Power Solutions, and ZincFive BMS. ZincFive says it has nearly 2 GW of systems deployed and contracted globally, plus about $81 million of backlog as of December 31, 2025. The market backdrop is favorable on paper: the company is pitching into data center growth, AI-driven power density increases, and UPS battery replacement and retrofit demand. In its materials, it cites a 2025E TAM of about $8.8 billion for new-build data centers and edge retrofit, a 2025A TAM of about $1.6 billion for UPS battery retrofit, and a 2025E potential opportunity of about $7.1 billion for AI power.
The SPAC Deal
ZincFive is merging with Spark I Acquisition Corp, which currently trades under the ticker SPKL. The deal values ZincFive at $600 million pre-money equity value and about $752 million pro forma enterprise value in the June 11, 2026 announcement, with later materials showing a similar but slightly higher $762 million enterprise value. The combined company is expected to trade on Nasdaq under the ticker ZFIV.
The trust account is small relative to the deal size: about $25 million at announcement, later cited as $26 million as of September 30, 2026. That makes redemption risk a real issue, although the transaction is anchored by a $100 million committed preferred equity PIPE, which the company says fully satisfies the minimum cash condition. The deal materials also say there is up to $25 million of additional proceeds depending on redemptions, and they reference a bridge loan of $5 million at signing in one presentation and $6.5 million in another, expected to be repaid at closing.
Dilution is a major part of the setup. The materials explicitly flag public and private warrants, preferred PIPE warrant coverage, SPAC founder shares, incentive shares transferred from the sponsor, and a convertible promissory note. One slide says the analysis excludes 13.5 million public and private warrants with an $11.50 exercise price, plus preferred PIPE warrant coverage. The transaction was announced June 11, 2026, the S-4 was filed September 30, 2026, and the latest filings say the deal is still pending. ZincFive’s August 13, 2026 425 said it expected to close in Q4 2026, while later materials say second half of 2026. Based on that timing, the estimated first-trading window is late 2026, assuming shareholder approval, SEC effectiveness, and closing all happen on schedule.

The SPAC route gives ZincFive a faster path to public markets than a traditional IPO, while also letting the company market forward projections in its merger materials. That matters here because the story is still early relative to the size of the opportunity: the company is using the de-SPAC to raise growth capital, support manufacturing scale, and fund the next phase of commercial expansion in data center and AI infrastructure power.
The merger also comes with sponsor backing and a committed financing package that helps bridge the gap between current cash and the capital needed to execute. ZincFive says existing equity holders are participating in the PIPE and will retain 100% of their equity into the combined company, which is a notable signal of insider support, even as the structure still leaves public investors exposed to SPAC-specific dilution and redemption mechanics.
Financial Highlights
ZincFive says revenue doubled from 2024 to 2025 to approximately $66.9 million, and later investor materials describe 2025A revenue growth of 126%. The company also says backlog was $81.2 million, and approximately 77% of 2026 forecast revenue was attributable to contracted backlog as of December 31, 2025. For 2026, the proxy materials include a projected revenue range of $90 million to $105 million; that is explicitly a projection, not reported results.
Losses are still heavy. The S-4 says ZincFive had a net loss of $120.2 million in 2025 versus $64.9 million in 2024. For the six months ended June 30, 2026, it reported a net loss of $51.2 million, cash used in operations of $36.2 million, and adjusted EBITDA loss of $24.5 million. Cash and cash equivalents were just $1.9 million at June 30, 2026 and $3.6 million as of September 25, 2026, with restricted cash of $3.2 million. The filing also says there is substantial doubt about the company’s ability to continue as a going concern without additional financing.
Risk Factors
The biggest de-SPAC risk is cash leakage from redemptions. Spark I had about $25 million in trust at announcement, later $26 million, but the S-4 says redemptions after the September 25, 2026 shareholder meeting amounted to up to approximately $11 million, and the amount available to ZincFive may be reduced further. Even with the PIPE, shareholders should watch whether the final cash stack is enough to support the business plan without additional financing.
Dilution is another major overhang. The deal includes public and private warrants, preferred PIPE warrant coverage, founder shares, incentive shares, and a convertible promissory note. On top of that, ZincFive is still loss-making, cash flow negative, and dependent on converting backlog into revenue while scaling manufacturing. The company also faces execution risk in a market tied to data center and AI infrastructure spending, plus the usual deal risk that SEC timing, shareholder approval, or closing conditions could still delay or derail the transaction.
Comparable Public Companies
The filing does not provide a clean named public comp list in the accessible text, but the closest public references for investors are battery and power-infrastructure names such as EnerSys (ENS), Flux Power (FLUX), Eaton (ETN), and Vertiv (VRT). Those names help frame the market’s willingness to pay for battery, UPS, and data center power exposure, even though ZincFive’s NiZn chemistry is more specialized than most of them.
The proxy’s battery peer analysis shows EV / 2026F revenue multiples ranging roughly from 6.6x to 55.9x, with a median around 14.3x and an updated blended multiple of 15.6x. That is a wide spread, which tells you the market is likely to reward growth and infrastructure exposure, but only if investors believe the company can scale without getting crushed by dilution or continued losses. For cross-linking, the public tickers to track are ENS, FLUX, ETN, and VRT.

This is a real AI infrastructure power story, not a generic battery SPAC. ZincFive has commercial traction, a meaningful backlog, and a differentiated NiZn product set aimed at data centers, UPS retrofits, and AI power density needs. That is why the deal matters now: it is trying to ride one of the strongest infrastructure themes in the market while still private enough to use projections and a sponsor-backed financing structure to get public.
But shareholders should watch the mechanics as closely as the story. The trust is small, redemptions can still shrink the cash delivered at closing, and the capital structure carries obvious dilution from warrants and sponsor-related shares. If the deal closes in the second half of 2026 as expected, the first public trading window is likely late 2026 under ZFIV. The setup favors investors who believe ZincFive can turn backlog into profitable scale; the main question is whether the post-merger balance sheet and dilution load leave enough upside for that thesis to work.
